Dear friend, welcome to HCM.
Pain in abdomen with nausea
has many causes.
Can you please describe in detail all the attriibutes of your pain?
If it is constant or colicky/ intermittent?
If more when hungry?
Is there acidity/ sour eructation?
You need to get evaluated by your physician and may need to do an ultrasound
abdomen to see the cause.
You can try OTC acidity medicines with anti emetic like ondansetron
I hope this helps your cause.
Keep me informed of your progress.
Good luck !
